and run Backdoor programs, they will find some methods to joke with the system administrator. This involves two aspects: how to hide his files and how to hide his processes. To hide files, intruders need to do the following: replace some common system commands such as "ls", "du", "fsck ". At the underlying level, they mark some areas in the hard disk as bad blocks and place their files there. Or if he is crazy enough, he will put some files into the boot block. To hide a process, he can repla

arrays should be prepared to prevent disk damage (security not only refers to system security, but also to data security and communication security) 　 17. the file integrity check tool tripwire is used to check the file integrity (so it is strongly recommended that the linux system administrator keep work notes during work and make changes to the settings in the modifications to system settings) do not save the integrity check data to the hard disk o

on whether the intruders "scan the end" and do enough work. For an intrusion that requires sufficient homework, it will be a matter of precision and pain to clean up. In this case, professional third-party tools (open-source, for example, tripwire or aide. Professional tools are difficult to deploy and use, and not all administrators can use them skillfully. In fact, the Linux system itself has provided a "Verification" mechanism, and the program

assessment. However, enterprises need to understand that this digital game does not need to be perfect, especially when it comes to evaluating the impact of security leaks. "The evaluation of the impact of security incidents makes it easier for enterprises to discuss and focus on how to mitigate risks, rather than spending a lot of time discussing whether the impact is worth $20 million or $21000, dwayne Melancon, chief technology officer of Tripwire

). From the Internet perspective, I will implement the appropriate inbound) Access Control List ACL) and try to restrict NAS. For example, using built-in firewall security restrictions can prevent traffic from untrusted interfaces, such as the Internet or DMZ, from flowing to trusted interfaces, such as the Intranet ). In addition, access to the network-oriented DMZ should be limited to the appropriate application ports, such as TCP port 80 and TCP port 443 ). Consider executing a strict outbo

, and port usage, and users will not be able to get real system situation reports. Rootkits Defense methods: The most effective method to defend against rootkits is to regularly check the integrity of important system files. There are many such tools, such as tripwire, which is a very good file integrity check tool. Once rootkits attacks are detected, it is troublesome. You must reinstall all System File Components and programs to ensure security. Her

system. -- Problems in traditional rootkit Detection Technology Traditional rootkit detection programs (which we often see in UNIX systems) can only detect known rootkit (which makes it look like an anti-virus program) or scan for some internal-core storage. for example, Linux has some tools to scan the syscall table in the kernel. this is obviously not good, because there are many rootkits that do not change syscall table, and similar rootkits can be developed in Win2k. Should the detection pr

many programmers in many service programs use functions similar to strcpy () and strcat () that do not perform a valid bit check, in the end, malicious users may write a short program to further open the security window and thenCodeEnd with the buffer payload. In this way, when a buffer overflow occurs, the returned Pointer Points to malicious code, so that the control of the system is captured.Defense: Use programs such as safelib and tripwire to pr

connections are usually allowed. Finally, we should record all the prohibited connections to detect possible attack attempts. However, broadcast and multicast data packets should be discarded because these data packets may soon be filled with system logs. The following is an example of ipchains configuration (protecting the independent server system ): Bash # ipchains-lChain input (Policy deny ):Target prot opt source destination portsDeny all ------ 0.0.0.0 anywhere N/Deny all ------ anywhere

DBIR called by SQL injection. The injection vulnerability is a very common security vulnerability. It is very easy to use without tools to use simple text commands.The best way to avoid Web-based attacks such as SQL injection is to prevent security programming practices in the first place, but security programming must occur during the development of Web applications. So Web applications may already include SQL Injection Vulnerabilities in production?Vulnerabilities in widely used Web applicati

The disadvantage of the above methods is naturally to invite SnappyDB, the main character of this article. SnappyDB is a key-value database and a very popular NoSQL database.
